Description

Technical Field

[0001] The utility model specifically relates to the technical field related to filters, in particular to a filter used before purification in a washing tower. Background Art

[0002] Waste gas refers to the toxic and harmful gases discharged by humans in the process of production and life. In particular, chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries emit waste gas with strong odor, polluting the environment and affecting human health.

[0003] Most of the waste gas treatment is done by introducing the waste gas into a washing tower and then spraying an absorbing liquid through a nozzle. The absorbing liquid and the gas are fully mixed, contacted, and chemically reacted to treat the waste gas.

[0004] Before treating the exhaust gas, the scrubber needs to filter out the dust in the exhaust gas. The existing scrubber needs to be equipped with a separate exhaust gas treatment device, but the filler or washing liquid in the scrubber needs to be replaced regularly, so it needs to be shut down for replacement, resulting in the inability to discharge industrial exhaust gas normally. Utility Model Content

[0005] The purpose of the utility model is to provide a filter for use before purification in a washing tower, which changes the transmission direction of the gas through a ball head shell and transports the gas to two washing towers through two gas pipes. When one of the washing towers needs to replace the filler or the washing liquid, the transmission state of one gas pipe is changed to the position of another gas pipe, thereby achieving non-stop operation and ensuring the normal transmission and treatment of industrial waste gas, so as to solve the problems raised in the above-mentioned background technology.
